SIMPLY AMAZING !!

I but this product at Home Depot for half of what Walmart sells it for. I use it for my 97 4RUNNER with 250, 000 miles. I don't know what they put in these tiny bottles but IT WORKS! I can easily notice the difference. Better performance, better power, smoother acceleration. The best $2 investment for better performance! I use a bottle every time I fill up.

Engine Knocking

Using this product second time in a row, my car is Honda city model 2006 done millage 150,000 km till now. I found drop in pick and my car engine knocking while running on road. Is this because of Gumout or some thing else.

Check engine light

Have been using this product on a regular basis. I use one bottle when the check engine light comes on in my 2005 Town and Country and the light goes out for months.
